AMD Radeon RX 9070 XT vs NVIDIA H20 Comparison

Where Each One Wins

The AMD Radeon RX 9070 XT and NVIDIA H20 are fundamentally different products serving different workloads, and the recorded data makes that split unambiguous. The RX 9070 XT is a graphics-first card with ten benchmark entries covering DirectX, OpenCL, Vulkan, and compute workloads. The NVIDIA H20 has no benchmark entries in the database, so every measurable performance comparison defaults to the AMD card. The RX 9070 XT wins all recorded tests by default, but those wins are concentrated in client-side graphics and general compute tasks. The H20, in contrast, is a server accelerator with no display outputs and no DirectX, OpenGL, or Vulkan API support, which means it cannot participate in the same benchmark suite at all.

The database shows the RX 9070 XT producing a Passmark G3D score of 26795, a Geekbench Vulkan score of 65879, and a 3DMark Steel Nomad DX12 score of 7260. These are the metrics that matter for gaming and workstation graphics. The H20 has zero recorded scores, so its strengths are not quantified in this dataset. The H20 instead offers 96 GB of HBM3 memory with 4.03 TB/s bandwidth, which the RX 9070 XT cannot match with its 16 GB GDDR6 and 644.6 GB/s. The H20 also has 312 tensor cores and 79.07 TFLOPS of FP16 throughput, pointing toward AI inference and large-model workloads, while the RX 9070 XT has no tensor cores and delivers 48.66 TFLOPS of FP16.

The use-case split is therefore clear: the RX 9070 XT wins every benchmark that exists in the database, while the H20 wins on memory capacity, memory bandwidth, and tensor-core capability, none of which are directly benchmarked here.

Head-to-Head Benchmarks

The head-to-head benchmark table in the database is empty, and the win counts for both cards are zero. This is because the NVIDIA H20 has no benchmark entries at all. The only comparable data comes from the RX 9070 XT's own benchmark suite, which shows a consistent performance profile across graphics and compute tests.

The RX 9070 XT records a 3DMark Steel Nomad DX12 score of 7260, which is its highest-profile graphics result. In Geekbench, the Vulkan score of 65879 far exceeds the OpenCL score of 17428, indicating strong Vulkan driver optimization. The Passmark suite shows a G3D score of 26795, a GPU compute score of 15864, and a G2D score of 1328. The DirectX sub-scores are 353 for DirectX 9, 292 for DirectX 11, 154 for DirectX 10, and 78 for DirectX 12. These numbers indicate that the card's older DirectX paths are relatively weaker, while its Vulkan and compute paths are much stronger.

The average benchmark score for the RX 9070 XT is 13543, placing it at the 55th percentile among all GPUs in the database. Its nearest rivals by average score are the AMD Radeon HD 7770M at 13536 (0.1% lower), the NVIDIA GeForce GTX 570 at 13515 (0.2% lower), the NVIDIA P106-090 at 13470 (0.5% lower), and the AMD Radeon Pro 555 at 13407 (1% lower). These deltas are tiny, meaning the RX 9070 XT's average score sits in a very crowded performance band, despite its high peak scores in specific tests. The discrepancy between the 55th percentile average and the high G3D score suggests the average is dragged down by the low DirectX sub-scores and the moderate G2D result.

The NVIDIA H20 has no recorded benchmarks, no average score, and no nearest rivals. Its percentile is listed at 50, but with an average benchmark score of zero, that percentile carries no measurable weight. The database cannot compute any head-to-head deltas because there is no data for the H20 side of the comparison.

Specification Differences

The two cards differ in nearly every specification category. The AMD Radeon RX 9070 XT uses a 4 nm process node, while the NVIDIA H20 uses 5 nm, both from TSMC. The H20 has 80,000 million transistors on an 814 mm² die, while the RX 9070 XT has 53,900 million transistors on a 357 mm² die. Transistor density is 151.0M per mm² for the AMD card versus 98.3M per mm² for the NVIDIA card.

Clock speeds diverge sharply. The RX 9070 XT has a base clock of 1660 MHz, a boost clock of 2970 MHz, and a game clock of 2400 MHz. The H20 has a base clock of 1830 MHz and a boost clock of 1980 MHz, with no game clock listed. The AMD card's boost clock is 50% higher than the H20's boost clock.

Memory specifications are completely different. The RX 9070 XT uses 16 GB of GDDR6 on a 256-bit bus at 2518 MHz (20.1 Gbps effective), yielding 644.6 GB/s. The H20 uses 96 GB of HBM3 on a 6144-bit bus at 1313 MHz (5.3 Gbps effective), yielding 4.03 TB/s. The H20's memory bandwidth is over 6 times higher, and its capacity is 6 times larger.

Compute unit counts differ as well. The RX 9070 XT has 4096 shading units, 256 TMUs, 128 ROPs, and 64 ray tracing cores, with no tensor cores. The H20 has 9984 shading units, 312 TMUs, 24 ROPs, and 312 tensor cores, with no ray tracing cores listed. Pixel rate favors the RX 9070 XT at 380.2 GPixel/s versus 47.52 GPixel/s for the H20. Texture rate is 760.3 GTexel/s for the AMD card versus 617.8 GTexel/s for the NVIDIA card.

Power and physical specs also differ. The RX 9070 XT has a TDP of 304 W, is dual-slot, uses 2x 8-pin power connectors, and suggests a 700 W PSU. The H20 has a TDP of 500 W, is an SXM module, lists no power connectors, and suggests a 900 W PSU. Both use PCIe 5.0 x16. The RX 9070 XT has 1x HDMI 2.1b and 3x DisplayPort 2.1a outputs, while the H20 has no display outputs.

Architecture Differences

The AMD Radeon RX 9070 XT is built on RDNA 4.0 architecture and belongs to the Radeon RX 9000 series, with the Navi 48 chip and the Navi IV (RX 9000) generation. Its predecessor is Navi III. The NVIDIA H20 is built on Hopper architecture with the GH100 chip, belonging to the Server Hopper (Hxx) generation. Its predecessor is Server Ada, and its successor is Server Blackwell.

The RDNA 4.0 architecture is designed for client graphics, with a 12 Ultimate DirectX feature level, Vulkan 1.4 support, and a full display output suite. The Hopper architecture is designed for server acceleration, with no graphics API support and no display outputs. The H20's 312 tensor cores are the key architectural differentiator, enabling FP16 throughput of 79.07 TFLOPS at a 2:1 ratio. The RX 9070 XT has no tensor cores and runs FP16 at a 1:1 ratio, delivering 48.66 TFLOPS.

The H20 also has a much larger die (814 mm² versus 357 mm²) and more transistors (80,000 million versus 53,900 million), but lower transistor density due to the larger process node. The RX 9070 XT compensates with higher clock speeds and a more graphics-oriented pipeline, including 64 ray tracing cores and 128 ROPs versus the H20's 24 ROPs and no ray tracing cores.

Release dates also differ: the RX 9070 XT launched on 2025-03-05, while the H20 launched on 2024-01-31. The RX 9070 XT has a launch MSRP of 599 USD, while the H20 has no launch MSRP listed.

The Verdict

The data supports a clear split. For any graphics workload that uses DirectX, Vulkan, or OpenGL, the AMD Radeon RX 9070 XT is the only viable choice, because the NVIDIA H20 has no support for those APIs and no display outputs. The RX 9070 XT's benchmark results confirm strong Vulkan performance (65879 in Geekbench Vulkan) and solid DirectX 12 performance (7260 in 3DMark Steel Nomad). Its FP32 throughput of 48.66 TFLOPS is 23% higher than the H20's 39.54 TFLOPS, and its pixel rate of 380.2 GPixel/s is 8 times higher than the H20's 47.52 GPixel/s.

For memory-bound or tensor-core workloads, the NVIDIA H20 is the only option with the required resources. Its 96 GB of HBM3 memory and 4.03 TB/s bandwidth dwarf the RX 9070 XT's 16 GB and 644.6 GB/s. Its 312 tensor cores and 79.07 TFLOPS of FP16 throughput are absent from the AMD card entirely. The H20's 500 W TDP and 900 W suggested PSU also indicate a server-class power envelope, while the RX 9070 XT's 304 W TDP and 700 W suggested PSU fit a desktop client.

The database shows no head-to-head benchmark results, so any direct performance comparison must rely on the specification differences and the RX 9070 XT's standalone scores. The RX 9070 XT sits at the 55th percentile among all GPUs with an average score of 13543, while the H20 has no average score. The nearest rivals to the RX 9070 XT are all within 1% of its average score, indicating that its average performance is not exceptional even though its peak graphics scores are strong.

The intended user base is equally clear. The RX 9070 XT targets desktop gaming and workstation graphics, with display outputs, graphics API support, and a 599 USD launch MSRP. The H20 targets server inference and compute, with no display outputs, no graphics APIs, and a much larger memory pool. Each card wins in its own domain, and the database cannot meaningfully rank them against each other because they share no benchmark results. The RX 9070 XT wins all recorded tests, but the H20's unrecorded capabilities in tensor and memory-bound workloads are the deciding factor for server buyers.
